Filed: 1936-12-31
Abstract: 468,500. Grease guns and syringes. TECALEMIT, Ltd. Dec. 31, 1936, No. 35872. Convention date, Dec. 31, 1935. [Classes 102 (i) and 102 (ii)] In lubricating - apparatus in which the lubricant reservoir or cylinder 'is charged by means of a lubricant cartridge of paper or other material of small resistance, the contents of the cartridge is transferred to the reservoir or cylinder by sliding the latter inside the former. As shown, the cartridge 6 has one end removed and an aperture 7 formed in the other end prior to inserting it in a casing 2. A cylinder 10 secured to a cover 9d is then slid into the cartridge so that the contents of the latter are expelled into the cylinder 10. The edge 10a of the cylinder 10 may be bevelled to have a scraping action, and it may also crush the rim 4 of the cartridge to render the joint tight. The lower portions of the casing 2, cartridge 6, and cylinder 10 may be conical. The cylinder 10 may have a piston 12<1> subjected to air pressure for discharging the grease into a pump cylinder 16. In a modification, applied to a syringe, the piston 12<1> has a screwed stem, the pump cylinder 16 being omitted. In another modification, the piston 12<1> is subjected to compressed air to discharge the grease into a high pressure compressed air actuated grease gun. In another modification, the piston 12<1> is secured to a hollow discharge tube so as to form a syringe actuated by direct manual pressure.

Abstract: 1,025,979. Frequency modulation. SIEMENS & HALSKE A.G. Sept. 16, 1963 [Sept. 28, 1962], No. 36290/63. Heading H3R. Modulation is applied through terminals 6 to reactor diodes 3, 2, in the frequency determining collector circuit of a transistor oscillator to produce frequency modulation. To improve the frequency modulation linearity a series resonant but highly damped circuit 18, 17, 16 is connected between a tapping of the collector inductor 1 and the oscillator load 16 and is resonant above the maximum frequency excursion of the oscillator, and so tends to reduce the total reactance of the collector circuit and assists in increasing the modulated frequency as the modulation increases it. The emitter circuit 11, 12 is also tuned and Ct is a feedback capacitor. A section of coaxial transmission line terminated by its surge resistance R may alone form the circuit 18, 17, 16, stray inductance forming the inductor 18. Also stray inductance of the coil 1 regarded as an auto-transformer may replace the inductor 18. The system may be applied to multiplex FM relay systems.

Abstract: 431,333. Coiling. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Zabel, W. P. ; 2060, Hanover Road, Cleveland Heights, Ohio, U.S.A.) Dec. 29, 1933, No. 36612. Convention date, Dec. 31, 1932. [Class 83 (iv)] [See also Groups XI and II] In a method of making coiled-coil filaments a filament wire is wound around a primary mandrel which is considerably less refractory than the filament, and the coil with its mandrel is then wound around a refractory secondary mandrel, the coiled structure thus formed being then heated to nearly a white heat to remove a considerable part of the strains in the primary coil, after which the primary mandrel is removed and the coiled coil on the secondary mandrel heated to approximately 2800 C., the secondary mandrel being removed finally. After the removal of the primary mandrel the filament is heated to a red heat, then to 2250 C. in approximately fifteen seconds, and then to 2800 C. in approximately a further thirty seconds. In the example a tungsten wire is first coiled around a steel mandrel, this coil next being wound around a secondary mandrel 12, Fig. 3, of tungsten wire. As shown, the secondary coil comprises a series of spaced segments 13 with an extra long space between consecutive groups of segments, each group constituting a filament. The primary coil 10 is secured, preferably by welding, to the secondary mandrel 12 at two points 15, 16 about half an inch apart between two groups of segments 13, 14, the welds being of nickel or other metal which does not dissolve in hydrochloric acid or strong alkalies. After welding, the coil is heated to a white heat, or about 1100 C., in an electric furnace in the presence of hydrogen, the mandrel 12 being either passed through the furnace, or the individual groups being first separated by cutting the mandrel between the welds 15, 16 before placing them in the furnace. The steel mandrel is next dissolved out in a hydrochloric acid solution, and the ends of the coil and mandrel assembly are clipped within the jaws 18, 19, Fig. 4, of a fixed terminal clip 17 on a hollow tube 30, and similar jaws 20, 21 on a clip 20 adjustably mounted on a hollow tube 43. The clips and coil assembly are enclosed in a hydrogen bottle 53 which has its open end sealed by a compressed rubber tube 58 within an annular groove 57 in a mounting-plate 31, a water jacket 64 being provided around the bottle 53. Terminal clips 51, 52 are secured on the tubes 30, 43 which conduct current to the mandrel 12 and coil 10. The tubes 30, 43 are cooled by circulating water therethrough. To compensate for expansion and contraction of the mandrel 12 the clip 20 is supported on a pair of bolts 47 which are secured in a block 48 and pass through a block 49 clamped on the tube 43, with coil springs 50 surrounding the bolts between the blocks 48, 49.

Title: Improvements relating to the production of metal chromates and chromate pigments
IPC: C01G37/14
Filed: 1957-06-03
Abstract: A water - insoluble manganese - containing chromate pigment is prepared by heating a water-insoluble material containing manganese both as manganese dioxide and manganous oxide; for example pyrolusite, with chromic acid or a soluble salt thereof in an amount not exceeding that required to react with the manganese compounds, other than manganese dioxide, present.  The chromic acid may be employed in the form of brines or tailings from bichromate manufacture.  An aqueous solution of the chromic acid or salt may be employed, and the heating carried out under pressure and at a temperature above the normal boiling point of the solution.  In a modification, part of the manganese-containing starting material is replaced by red lead or a lead-containing material that has been subjected to an oxidising roast to convert at least part of the lead to Pb3O4, and the amount of chromic acid or salt employed does not exceed that required to react with both the manganese and lead compounds, other than manganese and lead dioxide, present.  The lead-containing material may be anglesite-cerussite-calamine ore, lead battery dross, lead sulphate slimes, or galena.  Small quantities, for example 2%, of other insoluble chromates, for example those of zinc, calcium, strontium and barium, may be added to the pigment product before grinding for example to 5-20 microns.

Abstract: 643,660. Influence machines. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Dec. 13, 1946, No. 36900. Convention date, March 3, 1945. [Class 35] In an electrostatic motor or generator of the Toepler type the plates carrying the charge to the output collector terminal are first charged by association with one set of charged plates and then, as they yield this charge to the output collector are simultaneously deprived of a charge of opposite sign by association with a further set of charged plates. In its simplest form, Fig. 1, each of a pair of charge carrying plates 4, 5 pass in turn between a pair of conventional inductor plates 1, la, which are maintained at, say, a negative potential of - U, and then between an additional pair of plates 2, 2a which are kept at a potential of + 2U so as to abstract a negative charge from the movable plates. The rotating plates are con. nected to contact strips 8, 9 on a commutator 7 engaged by an earthed brush 10 and an output collecting brush 11. Each carrier plate is earthed as it passes between plates 1, la so that it leaves these with a positive charge. On passing between the plates 2, 2a a further negative charge is taken from it simultaneously with its making contact with the output brush 11 so that, when operating as a generator, the yield of positive charge is increased. The charged inductor plates may be energized from further electro-static machines in conjunction with the output of the machine itself. A modification having eight poles is also described and various values of inductor plate potential are given. The machines run in the reverse direction when acting as a motor.
